Hello,
I'm having problems trying to decode h264 video from IP camera, after some search I found it's because ffmpeg, so I downloaded the latest ffmpeg, and tried to link it to openCV but it still showing the old version! I read that this can be solved by recompiling openCV, so while trying to do so, I keep getting the following error: [part of the error, there are other files with same error]:

I found this problem can be solved by adding #include<algorithm> at the top of each header file showing such error, I did so, but the problem persists, also I'm not using visual studio, it's g++5 on ubuntu 14.04,
I appreciate your help! Regards
